Front End Mystery

[Sonar465@aol.com]

Dear Fellow Audi owners,
     I have a 1983 5KS with a problem tahhas baffeled me.  When first using
my car in the morning I get a strange vibration coming from the front end.
 It feels like a very out of balance tire but occurs at very low speed
(20-30MPH). Upon breaking I get a pulsing throught the break pedal feeling
like ABS gone wild.  The problen sorts itself out after a few minutes and
repeated breaking.  This morning I took the wheel off, started the car and
put it in gear (Don't try this at home). All seems normal except for an
occasional clicking sound.  I would say CV joints , but the tell tale signs
are not there (no clicking going around corners), I'm think the wheel bearing
might be shot but they were replaced jus a few thousand miles ago, and the
rotors do not appear warped.  I'm stumped, anybody out there have any
experience with somthing like this.

many other things which I will not go into now, But it still looks great)
